More studies are needed in tropical systems in order to assess contamination risks to non- target endemic tropical species from the extensive use of pesticides e.g. in banana and pineapple plantations. In this study, acute laboratory toxicity tests with organophosphate pesticides ethoprophos and chlorpyrifos were conducted on two Costa Rican species, cladoceranDaphnia ambigua and fish Parachromis dovii. Tests showed that chlorpyrifos was more toxic than ethoprophos toD. ambigua and P. Publication Info doviiand that D. ambigua was also more sensitive than P. dovii to both pesticides. Additionally, bioassays Paper received: were performed by exposingD. magna and P. dovii to contaminated water collected from the field. 27 April 2013 Chemical analyses of field water revealed that fungicides were generally the most frequent pesticide group found, followed by insecticides/nematicides and herbicides. The bioassays and values obtained from the literature confirmed thatD. magna was more sensitive to pesticide contamination thanP. dovii and that D. Revised received: ambiguawas more sensitive than D. magna , suggesting that the native cladoceran is a more suitable test 24 June 2013 species than its temperate counterpart. Species sensitivity distributions showed no significant difference in sensitivity between tropical and temperate fish and the arthropod species exposed to chlorpyrifos in this Accepted: study. Choline esterase activity (ChE) was measured inP. dovii in laboratory tests in order to assess the 05 September 2013 applicability of this biomarker. ChE inhibition inP. dovii was observed in the laboratory at levels below the LC10 of both ethoprophos and chlorpyrifos, confirming that ChE is an efficient biomarker of exposure. Both indigenous Costa Rican species used in this study were found to be suitable standard tropical test species. Further studies are needed to investigate how protective the safe environmental concentrations, derived from LC50 of native tropical species, are for protecting tropical aquatic natural communities.

Furthermore, pesticide pollution may result in species are suitable for toxicity testing and environmental risk acute and chronic effects on macroinvertebrates (Castillo et al., assessment in tropical regions. 2000), which could lead to changes in the benthic community structure and species richness (Pringle and Ramírez, 1998; Materials and Methods Castilloet al., 2006), and in turn change the food web structure.

    Habitat Complexity and Behaviour: Personality, Habitat Selection and Territoriality Kathleen Church A Thesis In the Department of Biology Presented in Partial Fulfilment of the Requirements For the Degree of Doctor of Philosophy (Biology) at Concordia University Montréal, Québec, Canada July 2018 © Kathleen Church, 2018 iii Abstract Habitat complexity and behaviour: personality, habitat selection and territoriality Kathleen Church, Ph.D. Concordia University, 2018 Structurally complex habitats support high species diversity and promote ecosystem health and stability, however anthropogenic activity is causing natural forms of complexity to rapidly diminish. At the population level, reductions in complexity negatively affect densities of territorial species, as increased visual distance increases the territory size of individuals. Individual behaviour, including aggression, activity and boldness, is also altered by complexity, due to plastic behavioural responses to complexity, habitat selection by particular personality types, or both processes occurring simultaneously. This thesis explores the behavioural effects of habitat complexity in four chapters. The first chapter, a laboratory experiment based on the ideal free distribution, observes how convict cichlids (Amatitlania nigrofasciata) trade-off the higher foraging success obtainable in open habitats with the greater safety provided in complex habitats under overt predation threat. Dominants always preferred the complex habitat, forming ideal despotic distributions, while subordinates altered their habitat use in response to predation. The second chapter also employs the ideal free distribution to assess how convict cichlids within a dominance hierarchy trade-off between food monopolization and safety in the absence of a iv predator. Dominants again formed ideal despotic distributions in the complex habitat, while dominants with lower energetic states more strongly preferred the complex habitat.

    35 ETHOPROPHOS (149) First draft prepared by Trijntje van der Velde-Koerts and Bernadette C. Ossendorp, National Institute of Public Health and the Environment (RIVM), Bilthoven, The Netherlands EXPLANATION Ethoprophos, a nematicide and soil-insecticide, was evaluated for residues in 1984 and in 1987. The toxicology of ethoprophos was periodically reviewed by the 1999 JMPR. Ethoprophos was listed as a priority compound under the periodic re-evaluation programme of the 30th Session of the CCPR (ALINORM 99/24 App VII) for residue review by the 2001 JMPR. The manufacturer requested the postponement of the residue evaluation. The basic manufacturer supplied information on identity, metabolism and environmental fate, residue analysis, use pattern, residues resulting from supervised trials on strawberry, banana, cucumber, melon, pepper, tomato, potato, sweet potato and sugar cane, fate of residues during storage and in processing, residues in food in commerce or at consumption and national maximum residue limits.

Despite their usefulness, these insecticides can pose a dangerous risk to the safety of food, environment and all living things through various mechanisms of action. Concern about the environmental impact of repeated use of insecticides has prompted many researchers to develop rapid, economical, uncomplicated and user-friendly analytical method for the detection of insecticides. In this regards, optical sensors are considered as favorable methods for insecticides analysis because of their special features including rapid detection time, low cost, easy to use and high selectivity and sensitivity. In this review, current progresses of incorporation between recognition elements and optical sensors for insecticide detection are discussed and evaluated well, by categorizing it based on insecticide chemical classes, including the range of detection and limit of detection. Additionally, this review aims to provide powerful insights to researchers for the future development of optical sensors in the detection of insecticides.
